IMPROVEMENT IN WASH-BOILERS.

Specification forming part of Letters Patent No. 140,936, dated July 15, 1873 application filed March 1, 1873.

To all whom it may concern:

Be it known that I, EDWARD H. MCDONALD, of Wytheville, Virginia, have invented certain new and useful Improvements in Wash- Boilers, of which the following is a specification:

The nature of my invention relates to an improvement in wash-boilers; and it consists in the arrangement and combination of parts which will be more fully described hereafter.

Figure l is a longitudinal vertical'section of my boiler. Fig. 2 is a section of the same as adapted to a common wash-kettle.

A B represent the ordinary false bottom for wash boilers, up through the center of which extends the tube a for conducting steam from the bottom of the boiler up into the condensing-chamber D placed on top. The chamber D is intended to be partially filled with water, which will be raised to a boiling-point by the steam from the boiler below, and is provided with the removable tube 2, which extends up to the top of the boiler and the stationary tube, through which the water is forated plate, E, which prevents the clothes from rising up against its bottom, in such a manner as to prevent the action of the steam from having its full efi'ect upon them. Through the side of the boiler there are two openings, m n, the upper one of which acts as a testtube, so that by removing its plug it can at once be seen how the water is boiling, and the other acts as a discharge.

The operation is as follows: A sufficient quantity of water and soap having been placed under the false bottom, the clothes packed in upon top of it, and the condenser filled with water, with the tube 2 in place, it is ready for operation. As the water begins to boil, the steam is driven through the holes in the part B, out through the clothes, and up through the tube 0 into the condenser D. As the steam is driven upward and outward through the clothes, it passes over to the sides of the boiler, where it is condensed and at once passes down into the false bottom again, to be again driven out through the clothes. After the clothes have been boiled sufficiently long, the plug is taken out of the tube a, and the water, dirt, and steam are all driven out through it into a tub placed for their reception. At the same time the plug is removed the tube 2 is taken out, when the water in the condenser begins to run down into the boiler below through the tube 0, the mouth of the tube being contracted-- so as to allow the water to escape only as fast as it can be converted into steam By keeping the condenser supplied with hot water, this operation of steaming the clothes can be kept up as long as may be desired, and when finished the clothes need only to be wrung out.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The condenser D, provided with the tubes,

2 3 and perforated plate E, substantially as set forth, in combination with the boiler F.

2. The false bottom A B, boiler F, condenser D, tubes 0 2 8, and discharge a, substantially as shown and described.
